james strachan commented on AMQ-674: ------------------------------------ BTW in 4.x the queue dispatch mechanism has been completely changed so that we can deal with massive queues with millions of messages on them; we don't have to keep around the entire queue contents in RAM in 4.x so you should not see the "WARN Queue is full, waiting for it to be dequeued. " messages in 4.x > Composite Destination persisted messages never get cleaned up, halt message > producers > ------------------------------------------------------------------------------------- > > Key: AMQ-674 > URL: https://issues.apache.org/activemq/browse/AMQ-674 > Project: ActiveMQ > Type: Bug > Components: Broker, Message Store > Versions: 3.2.1 > Reporter: Paul Smith > Priority: Blocker > Fix For: 4.0 RC1 > > > well, we've just got bit by something huge. > Previously we have been shipping messages from producer to consumer via a > named Queue 'Index2.EntityIncrementalIndexer', where the machine index2 has a > consumer called "EntityIncrementalIndexer" using persisted messages. > The design used Composite destinations so that the destination could be: > "Index1.EntityIncrementalIndexer,Index2.EntityIncrementalIndexer" > and have the 2 hosts get sent the same message simply, and if one goes down, > it'll catch up later. This gave us the ability to have a mirrored > configuration, and go tertiary later if we want simply by adding a new name > in the composite destation. > With a single name, this works great, been working fine for months. > Yesterday we activated the _true_ composite destination, and both machines > started getting their messages fine. > no problems so far, BUT, 12 hours later we have noticed that the broker has > now stopped accepting messages, and a look at the activemq_msgs table shows > 33228 messages -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://issues.apache.org/activemq/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
